Each of these types has many sub-groups. Stony Meteorites. Stony meteorites are made up of minerals that contain silicates —material made of silicon and oxygen.

Meteorites are fragments of asteroids or comets that have entered Earth's atmosphere and reached the ground intact. Scientists analyze their chemical and mineralogical properties for clues as to how Earth and other bodies in our solar system formed. They range in size from dust-sized particles to large masses.
